SPINNING-SPINDLE AND SUPPORT THEREFOR.

SPECIFICATION vforming part of Letters Patent No. 501,792, dated July18, 1893.

Application filed March 22, 1893. Serial No. 467,161. (No model.)

To all whom it may concern,.-

ABe it known that I, HENRY D. KLOTS, a citizen of the United States,residing in the city, county, and State of New York, have invented acertain new and useful Improvement in Spinning-Spindles and SupportsTherefor, of which the following is a specification.

My invention relates to means for enabling a spinning spindle toaccommodate itself in its rotation to an unbalanced load, and thereby toprevent vibration and its resulting disadvantages. Among the manydevices heretofore contrived for this purpose have been a universallyyielding mounting for the bolster-bearing of the spindle, for thestepbearing, or for both. A spindle has also beenV proposed having aiexible portion intermediate the bolster-bearing and bobbin-holdingportions. But none of these devices have been wholly successful inpreventing the in- I have disjurious vibration of the spindle. coveredhowever that by mounting a spindleblade constructed with a springintermediate the bobbin-holding and bolster-bearing portions, in abearing yieldingly connected to the rail, the flexibility of said springand yielding connections of the said bearing act in a novel manner totake up and remove both the local and bodily vibration of the spindledue to an unbalanced load. I have achieved the best results by using acombined bolster and step-bearing tube mounted on a universal springpivot joint of the character described in Letters Patent No. 493,034,issued to me March 7, 1893, for a spindle support.

' I shall first describe in detail the mode in which my invention iscarried into practice and then distinctly claim the same.

Reference is to be had to the accompanying drawings forming part of thisspecification in which- Figure 1 is a sectional elevation of a spinningspindle and its support embodying my invention. Fig. 2 is a sectionalplan view of the same on the line 2-2, Fig. 1.

Corresponding parts are designated bylike letters of reference in bothfigures.

A designates the spindle rail, B an attachable portion thereof, and C arigidly conlbined bolster and step-bearing tube for the spindle-blade F.I mount the bearing tube C, by preference as before stated, in therailportion B, on a universal spring pivot-joint D, of the generalcharacter described in my aforesaid Letters Patent issued March 7, 1893,so that every point of the spindle bearing tube will move in a circledescribed about the center of said universal pivot-joint D. The bearingtube C is here shown upheld by several radially arranged springs Ebearing laterally against the tube. The lower portion of thespindle-blade F is mounted in the bolster-bearing C and step-bearing C2of the tube C, but above the bolster-bearing C' the spindle-blade, withthe whirl G, is free to play laterally in all directions, thespindle-blade being constituted thereat and below the bobbin-holdingportion F, with aspring II, which may be rigidly attached to the ends ofthe bolster-bearing and bobbin-holding portions of the blade, or formedby reducing the diameter of the spindle bladeto one-eighth orthree-sixteenths of an inch according to the previouslydetermined temperof the metal. The spring H accommodates and takes up what I term thelocal vibration in the spindle due to an unbalanced load and transformsthe same into what may be called a bodily vibration, which it transmitsto the bolster bearing portion of the spindle and thence to thebolster-bearing tube where it is finally and fully taken up by thedescribed yielding connection of the said tube to the rail. In otherwords, the spring H transmits the average or resultant of the local,that is, waves of vibration in the spindle in the form of a bodilyvibration to the yielding connection of the spindle bearing.

Continued use by me of this self-springing spindle in combination withthe yieldingly mounted combined bearing tube C, has demonstrated that itcan be run at speeds three without appreciable vibration.

1. The combination, with a spindle bearing, its support and its yieldingconnection thereto, of a spindle blade composed of an upperbobbin-carrying portion, a lower bearing portion and of a springintermediate said bobbin-holding and bearing portions to cooperate withthe yielding connection of the bearing, substantially as described.

2. The combination, with a rigidly combined times as great as canordinarily be employed IOO bolster and step-bearing tube, its supportand its yielding connection thereto, of a spindleblade composed of anupper bobbin-carryingportion, a lower bolster-bearing portion and 5 aspring intermediate said bobbin-holding and bolster-bearing portions tocooperate with the yielding connection of the bearing tube,substantially as described.

3. The combination, with a rigidly combined ro bolster and step-bearingtube mounted. on a universal spring pivot-joint of the characterVitnesses:
